Title: A rack and pinion drive mechanism
IPC: F16H19/00
Filed: 1978-07-27
Abstract: A rack and pinion drive mechanism comprises a pinion (30) having three equiangularly spaced parallel pins (50A, 50B, 50C) all radially equidistant from the rotary axis of the pinion and adapted to mesh with the rack (20). The rotational movement of the pinion is subject to constraint by a guide formation so that, in use, the user experiences a substantially even loading when turning the pinion to displace the rack. The mechanism has a self-locking action which enables it to be used for adjusting components relative to one another (for example, reclining the backrest of a vehicle seat relative to the seat base) thereby avoiding the need for a separate locking device to hold the components in a selected position of adjustment. <IMAGE>

Title: Optical Fibre Splice
IPC: G02B6/38
Filed: 1978-08-15
Abstract: For joining two optical fibres, especially under field conditions, it is known to use a surface with a V- groove machined or otherwise produced in the surface, the two fibre ends being butted together in the groove. In the present arrangement, an alignment guide of the above type is made by placing two or more glass rods 1, 2 together with their axes parallel and their surfaces touching; and pulling them while they are heated. This produces a V-groove alignment guide the sides of which are curved. The use of glass rods means that the alignment guides are relatively cheap and are of a material compatible with that of the fibres. <IMAGE>
